[PHP] Installing Imagemagick on Windows
Hi, I need help with installing Imagemagick on Windows. I tried googling but there is no solution provided. I discovered that a lot of people are having the same problem as me. After placing the dll in the extension folder and adding in extension=php_imagick.dll into php.ini, Apache will hit error Unknow(): Unable to load dynamic library F:\php\extensions\php_imagick.dll. I believe that my php.ini is configured correctly. I am able to load other extensions with out any error. This is what is in my php.ini file extension_dir = "F:\php\extensions\" extension=php_imagick.dll What should I do with the ImageMagick library? Is there a step by step guide on installing imagemagick? With versions of library and links to download them?

[PHP] Socket warning
Hi all,
I programmed a server to bind to an external server(Let's call it
C-server). My server will have to listen on the connection to C-server
and send over data frequently. Each write of data to C-server from my
server will cause C-server to response a string.
So the codes will be something like this:
if($response)
{
socket_write($read_socket, "$response", strlen($response));
echo $response."\n";
}
...
some processing to construct string to be send over
...
foreach($message as $part)
{
socket_write($this->c_socket, $part);
echo $part."\n";
$out = socket_read($this->c_socket, 1024);
echo $out."\n";
error_log($part.":".$out."\n", 3, $this->logfile);
}
Everytime the execution reaches socket_write($this->c_socket, $part);
a php warning is issued
Warning: socket_read() unable to read from socket [11]: Resource
temporarily unavailable in
/var/www/html/dreamscape_mg/connectors/celcom/mo.php on line
134
Line 134 is the curl brace after the foreach. I am assuming that the
socket read would be $out = socket_read($this->c_socket, $part). Why do
I get the warning? c_socket is non blocking.
Thanks for your help

Re: [PHP] Use a Server or Client Socket?
Hi, I need to be polling the connection constantly for new messages as well as have a check that the connection is on. These need to be done in one connection. That's where the headache comes in. In order to poll constantly, I placed the socket read in a while loop. Since the script is looping constantly there, I can't place the checking in the while loop. And I can't make a need connection to check if I am still login because the external server only allows one connection. Raditha Dissanayake wrote: Hi, If you only need to make a connection to the server every ten minutes you will be saving a lot of resources if you use a cron job to connect at intervals instead of keeping a permanently open connections. Creating a cron job is quite simple, if you type man 5 crontab you will be able to read more about it (at least in linux - a poor substitute exists in windows called scheduled tasks) With this approach you just need to call fsockopen to do connect to your server and do the needful.

Hi Raditha,
Thanks, I have a better idea of how to write the codes. But I wonder, to
check that the connection to the external server is on, where should I
place the code? I need to do this every 10 minutes. If the connection is
dropped, I have to reconnect. Where should I place this check? If I
place it in the while(true) loop, I will be checking every few

Hi all,
I have this situation now that requires socket programming. But I am not
sure how to realise the requirements in programming whether as a
client or
server
The requirement is like this.
I have to connect to an external server constantly to listen for incoming
data. How can I make sure that the connection is there all the time? Upon
receiving the message, I will have to response back an acknowledgement
that
the message is received. I can also send data to the server. From my
requirements, I understand that there will only be one connection.
Therefore
the data exchange need not be in sequence.
Currently, what I have is a server programmed using the socket library.
Server logic :
socket_create
socket_bind
socket_listen
while(true)
{
socket_select
if(new connection)
{
add to connections array
}
else
{
if(can read)
{
read incoming
response back
}
else
{
//error or connection close
if(error)
{
print error
}
else
{
print connection close
remove from connections array
}
}
}
}
I am planning to include a check somewhere in the codes for
maintaining the
connection between my server and the other server. Where should I
place it?
Also, I need to initiate a connection to the external server and then
listen. Where should this piece of code be insert at? Is this the right
approach? Or I am over killing by writing a server if this can be
handle in
easier manner.
Hope that I have been clear in the above.
Thanks for helping

[PHP] Re: rich text editing
You can also use dhtml/js to code a html editor. But it will work in IE only. Search for online html editor. See this link:http://msdn.microsoft.com/library/default.asp If you are developing for a organisation, the type of browser used is easy to predict. If you are developing for the general public, there is of course other browsers to take care of. Java will fit all kind of browsers (that have java plugin) but it is usually very heavy for the client side.
